Oh-geez-golly-yes I'm playing with this, and I haven't had so much fun with tutorials since I don't know when!!! The interface for setting up bones and structures is so simplistic that it's a wonder how anyone tried to build characters in C before this! Give me some time for the models, but I think I got the interface down! The rendering is sped up a lot more. My little 650MHz/256MB AMD machine just gobbled through one of my older renders in record time (approx 10-25% faster, I think). This is a plus! The Caustics and illumination will have to wait, but litst and the others have already shown that feature and I can't wait to try it. I know others will have more to say than I, but this opinion coming from a relative duffer at this, it's a lot more friendly than, say, LW, and a lot cheaper!
